Chosei Onsen

Chosei Onsen flows in the rural southern reaches of Chiba Prefecture where the Chosei district's agricultural landscape of tea gardens, forested ridges, and Pacific coast scenery creates one of the most quietly beautiful environments in the entire Boso Peninsula, known among cycling enthusiasts as a destination for round-island tours that traverse farmland, sea views, and the gently rolling terrain of the peninsula's southern tip. The Pacific coast of the Chosei area faces directly toward the open ocean without the protection of the Kujukuri surf break further north, creating dramatic sea cliff scenery and conditions attractive to fishing communities that have worked these waters for generations. The onsen's siliceous geothermal waters, rising from the mineral-rich geology of the southern Boso Peninsula, provide restorative bathing in a rural corner of Chiba that rewards visitors willing to venture beyond the peninsula's more touristed northern beaches into the quieter south.
